-## Getting Started
+## Running Tests
+
+You can run tests by running the following command:
+
+```sh
+ash test $module-to-test
+```

+Where `$module-to-test` is either a module alias, or a module package.
+
+## Hooking Up a Module to Travis
+
+You can generate the `.travis.yml` file by running the following command while in your modules directory:
+
+```
+ash test:travis
+```
+
